Excerpt: ... in this section, and the confusion of red petals with green leaves, to which the author has referred, as proving the obscurity of red to Mr Troughton's eyes, is so nearly universal among the colour-blind, that I may. thus far adduce Sir David as at one with me in regarding red as appearing dark or darkish when seen by them. He holds, however, also, it will be seen, the remarkable opinion that the red light of the spectrum may appear much brighter, instead of much darker, to a colour-blind eye than to a normal one, in consequence of the former not perceiving the red, but instead thereof, yellow light of the same refrangibility, which makes a much stronger impression upon the retina. Additional observations can alone determine whether the anticipated phenomenon ever occurs. Its occurrence, however, would not be at variance with the appearance of red or crimson bodies as black to a colour-blind eye, as they do not transmit or reflect yellow rays to affect the retina. It is otherwise with scarlet bodies, which should appear as bright yellow to eyes which simply ignored red. But it is with green, not with yellow, that scarlet is systematically confounded by the colour-blind, as a review of all the recorded cases will fully demonstrate, and the green thus identified with scarlet is not a pale or yellowish green, but a full, and often dark, shade of that colour. Thus, Dalton compared sealing wax to one side of a laurel leaf, and a red wafer to the other, and his doctor's scarlet gown to the leaves of trees; nor was his case in this respect peculiar, for the colourblind are constantly found unable to distinguish the petals of the scarlet geranium from its leaves, the flowers of the wild poppy from the unripe corn amongst which it is growing, and...

Available in PDF, EPUB and Kindle. Book excerpt: Colour, Art and Empire explores the entanglements of visual culture, enchanted technologies, waste, revolution, resistance and otherness. The materiality of colour offers a critical and timely force-field for approaching afresh debates on colonialism. This book analyses the formation of colour and politics as qualitative overspill. Colour can be viewed both as central and supplemental to early photography, the totem, alchemy, tantra and mysticism. From the eighteenth-century Austrian Empress Maria Theresa to Rabindranath Tagore and Gandhi, to 1970s Bollywood, colour makes us adjust our take on the politics of the human sensorium as defamiliarising and disorienting. The four chapters conjecture how European, Indian and Papua New Guinean artists, writers, scientists, activists, anthropologists or their subjects sought to negotiate the highly problematic stasis of colour in the repainting of modernity. Specifically, the thesis of this book traces Europeans' admiration and emulation of what they termed 'Indian colour' to its gradual denigration and the emergence of a 'space of exception'. This space of exception pitted industrial colours against the colonial desire for a massive workforce whose slave-like exploitation ignited riots against the production of pigments - most notably indigo. Feared or derided, the figure of the vernacular dyer constituted a force capable of dismantling the imperial machinations of colour. Colour thus wreaks havoc with Western expectations of biological determinism, objectivity and eugenics. Beyond the cracks of such discursive practice, colour becomes a sentient and nomadic retort to be pitted against a perceived colonial hegemony. The ideological reinvention of colour as a resource for independence struggles make it fundamental to multivalent genealogies of artistic and political action and their relevance to the present.

Download or read book Colour Vision Deficiencies XI written by B. Drum and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The eleventh Symposium of the International Research Group on Colour Vision Deficiencies (IRGCVD) was held 20-23 June 1991 in Sydney, Aus tralia, ably hosted by local organizer Stephen Dain. A total of 35 talks and 10 posters were presented. Papers based on 37 of these presentations are included here, in Colour Vision Deficiencies XI. The scientific program featured sessions on three special topics, with each topic highlighted by an invited speaker. The opening session on the Genetics of congenital colour vision deficiencies began with a superb invited lecture by Charles Weitz about his pioneering work on the molecular genetics of tritanopia. The session on the second special topic, Spatial aspects of colour vision, began with the launching of a new IRGCVD tradition, as 1991 Verriest Memorial Award recipient Harry Sperling presented the first Ver riest Memorial Lecture on his recent studies of spatial discrimination of heterochromatic stimuli. Dr. Sperling reported new evidence that certain asymmetries in red-green opponent colour vision can be explained by the spatial organization of colour-opponent retinal neurons. In the third special session, on Occupational aspects of colour vision, Barry Cole took the audi ence on a fascinating tour of the historical development of colour vision standards in his invited lecture entitled 'Does defective colour vision really matter?'. In addition to the three special topics, many interesting presentations were given in topical sessions on Variations in normal colour vision, Acquired colour vision deficiencies and Colour vision tests and testing methods.

Available in PDF, EPUB and Kindle. Book excerpt: The Republic of Color delves deep into the history of color science in the United States to unearth its origins and examine the scope of its influence on the industrial transformation of turn-of-the-century America. For a nation in the grip of profound economic, cultural, and demographic crises, the standardization of color became a means of social reform—a way of sculpting the American population into one more amenable to the needs of the emerging industrial order. Delineating color was also a way to characterize the vagaries of human nature, and to create ideal structures through which those humans would act in a newly modern American republic. Michael Rossi’s compelling history goes far beyond the culture of the visual to show readers how the control and regulation of color shaped the social contours of modern America—and redefined the way we see the world.

Available in PDF, EPUB and Kindle. Book excerpt: Leading philosophers and scientists consider what conclusions about color can be drawn when the latest analytic tools are applied to the most sophisticated color science. Philosophers and scientists have long speculated about the nature of color. Atomists such as Democritus thought color to be "conventional," not real; Galileo and other key figures of the Scientific Revolution thought that it was an erroneous projection of our own sensations onto external objects. More recently, philosophers have enriched the debate about color by aligning the most advanced color science with the most sophisticated methods of analytical philosophy. In this volume, leading scientists and philosophers examine new problems with new analytic tools, considering such topics as the psychophysical measurement of color and its implications, the nature of color experience in both normal color-perceivers and the color blind, and questions that arise from what we now know about the neural processing of color information, color consciousness, and color language. Taken together, these papers point toward a complete restructuring of current orthodoxy concerning color experience and how it relates to objective reality. Kuehni, Jameson, Mausfeld, and Niederee discuss how the traditional framework of a three-dimensional color space and basic color terms is far too simple to capture the complexities of color experience. Clark and MacLeod discuss the difficulties of a materialist account of color experience. Churchland, Cohen, Matthen, and Westphal offer competing accounts of color ontology. Finally, Broackes and Byrne and Hilbert discuss the phenomenology of color blindness. Contributors Justin Broackes, Alex Byrne, Paul M. Churchland, Austen Clark, Jonathan Cohen, David R. Hilbert, Kimberly A. Jameson, Rolf Kuehni, Don I.A. MacLeod, Mohan Matthen, Rainer Mausfeld, Richard Niederée, Jonathan Westphal

Book excerpt: The development of ophthalmology to its present level of sophisticated practice is an extraordinary story of research, experiment, and achievement. Dates in Ophthalmology: A Chronological Record of Progress in Ophthalmology over the Last Millennium charts the progress of that achievement over the last millennium, highlighting and describing the key dates of advancement. It presents a concise listing of the chief personages, periods, publications, and events in the history of ophthalmology from ancient times to the present. The book demonstrates how ideas, discoveries, and technologies cross borders and oceans. It illustrates the interplay of subspecialties, the changing pre-eminence of countries and cities, and the explosions of creativity and generations of dormancy in various areas. The author highlights the numerous and diverse events and people responsible for shaping this specialty. There are many ways of looking at history: from the standpoint of the lives of major figures, of society and impact, of subspecialties, of countries, of institutions, and of books. By presenting its information chronologically, Dates in Ophthalmology explores the how these areas intersect, influence, and impact each other.

This book was released on 1990-10-26 with total page 836 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a comprehensive edition of Maxwell's manuscript papers published virtually complete and largely for the first time. Maxwell's work was of central importance in establishing and developing the major themes of the physics of the nineteenth century: his theory of the electromagnetic field and the electromagnetic theory of light and his special place in the history of physics. His fecundity of imagination and the sophistication of his examination of the foundations of physics give particular interest and importance to his writings. Volume I: 1846-1862 documents Maxwell's education and early scientific work and his major period of scientific innovation - his first formulation of field theory, the electromagnetic theory of light and the statistical theory of gases. Important letters and manuscript drafts illuminate this fundamental early work and the volume includes his letters to friends and family, general essays and lectures and juvenilia.
